Detailed Description
The following description of the embodiments of the present utility model will be made more fully hereinafter with reference to the accompanying drawings, in which it is evident that the embodiments thus described are only some, but not all, of the preferred embodiments of the present utility model. It should be understood by those skilled in the art that these embodiments are merely for explaining the technical principles of the present utility model, and are not intended to limit the scope of the present utility model.
Example 1 please refer to fig. 1-5;
The utility model provides a position adjusting mechanism of a heating device for spraying the inner wall of a pipeline, which comprises a base 8 for hanging a plurality of heating devices 5, wherein the base 8 is provided with a hollow cavity, two sliding groove groups penetrating through the front side and the rear side of the base 8 are formed in the base 8, each sliding groove group comprises two arc-shaped sliding grooves, namely a first sliding groove 81 and a second sliding groove 82, the two first sliding grooves 81 and the two second sliding grooves 82 are respectively symmetrical left and right by taking the middle position of the base 8 as a reference, a first sliding rod 9 and a second sliding rod 7 are respectively inserted into the first sliding grooves 81 and the second sliding grooves 82, the two ends of the first sliding rod 9 and the second sliding rod 7 extend out of the front side and the rear side of the base 8, the heating devices 5 are respectively connected with the tail ends of the first sliding rod 9 and the second sliding rod 7, the heating devices 5 are respectively connected to the front side and the rear side of the base 8, the two sliding grooves 6 are respectively fixedly arranged in the middle of a pair of the first sliding grooves 9, the two sliding grooves 6 are respectively positioned in the cavity, the centers of the two sliding grooves 6 are respectively provided with screw holes 4 in opposite screw directions, and the screw heads 4 are respectively screwed in the screw heads 4 to be screwed and screwed into the screw heads 4 when the screw heads are connected with the screw heads 4 in the screw heads through screw heads.
In order to clearly explain the operation of the present embodiment, the diameters of the steel pipes 1, 2, 3 shown in fig. 1 are 5m, 4m, 3.6 m, respectively.
The working principle comprises that the heating devices 5 are symmetrical front and back on the left side, the heating devices 5 are symmetrical front and back on the right side, and the four heating devices 5 are distributed along the arc line of the inner wall of the heated pipeline, and the inner wall of the pipeline passing through is heated when the pipeline rotates. When the inner diameter of the pipeline is changed, for example, when the steel pipe 3 is replaced by the steel pipe 1, the screw 4 is rotated, the pair of sliding blocks 6 with opposite spiral directions are firstly mutually opened, the pair of sliding blocks 6 drive the pair of first sliding bars 9 to mutually open, and meanwhile, the distance between the first sliding bars 9 and the second sliding bars 7 connected with the same heating device 5 is unchanged under the restriction that the heating device 5 is a rigid body. When the pair of first slide bars 9 are opened to each other, the pair of second slide bars 7 are also slid along the second slide grooves 82 to be opened to each other, so that the two groups of heating devices 5 which are symmetrical to each other are swung symmetrically to each other with the middle position of the base 8 as a reference. As can be seen from fig. 5, the focal points of the center lines of the two sets of heating devices 5 move upward, and the focal points, when located at the center of the steel pipe 1, complete the position adjustment of the two sets of heating devices 5. The tail end of the first sliding rod 9 is rotatably connected with the heating device 5, so that when the heating device 5 swings, the first sliding rod 9 does not rotate, the axis of the two screw holes is guaranteed to coincide, and the screw 4 is always inserted into the two screw holes. It can be seen that the screw 4 is used for adjusting the positions of the two groups of heating devices 5, so that the screw is quick and convenient, the bolts do not need to be frequently disassembled and assembled, the workload is small, and the main components of the adjusting mechanism are all positioned in the base 8, so that the structure is compact, and the occupied space is small. In addition, the position of the heating device 5 is adjusted by swinging, so that the device can adapt to the change of the diameter of the steel pipe in a large range and has a large application range.
In order to improve the heating efficiency, a group of mounting holes 83 penetrating through the front and rear sides of the base 8 are provided in the middle of the base 8, and the two heating devices 5 are fixedly mounted on the front and rear sides of the base 8 through connecting bolt assemblies on the mounting holes 83. It can be seen that the group of heating devices 5 in the middle position are fixed, do not need to be adjusted, avoid frequently disassembling and assembling the bolt assembly, and the center line of the bolt assembly is vertical upwards, and the center line of the bolt assembly always intersects the center of the steel pipe no matter how the diameter of the steel pipe changes.
Wherein the heating device 5 may be fixedly connected, e.g. welded, to the first slide bar 9 and the second slide bar 7. However, in order to facilitate maintenance, detachable threaded connection is preferred, and an exemplary threaded connection is that two connecting holes corresponding to the first sliding rod 9 and the second sliding rod 7 are formed in the heating device 5, the outer ends of the first sliding rod 9 and the second sliding rod 7 are respectively inserted into the two connecting holes, external threads are formed at the tail ends of the first sliding rod 9 and the second sliding rod 7, and two locking nuts are screwed on the external threads to detachably connect the heating device 5 with the tail ends of the first sliding rod 9 and the second sliding rod 7.
The key point is that the locking nut is not only detachable, but also further enables the first slide bar 9 and the second slide bar 7 to be fixed with the base 8 more firmly, when the locking nut is screwed down, the pressing force of the locking nut forces the heating device 5 to be tightly pressed against the side surface of the base 8, and the posture of the heating device 5 is more stable through the friction force between the base 8 and the heating device 5.
In order to facilitate the screwing operation of the screw 4, the side wall of the base 8 is provided with a window 84 corresponding to the screwing head 41. More preferably, the screw 4 is provided with the screwing heads 41 at both ends, the window 84 is provided on both opposite side walls of the base 8, and the screwing heads 41 extend out of the base 8 through the window 84. Thereby the screw 4 can be screwed from both sides of the base 8, which is more convenient.
When in use, the locking nuts on the two groups of heating devices 5 which are bilaterally symmetrical are firstly unscrewed, and the degrees of freedom of the two groups of heating devices 5 are released. Then, the screw 4 is rotated by using a spanner tool to drive the pair of sliding blocks 6 to open, the sliding blocks 6 drive the pair of first sliding rods 9 to open mutually, and under the cooperation of the second sliding groove 82 and the second sliding rod 7, the posture of the heating device 5 swings until the gap between the bottom of the heating device 5 and the inner wall of the heated steel pipe is uniform, and the focus of the central lines of the two groups of heating devices 5 can be considered to be positioned at the center of the steel pipe and adjusted in place. At this time, due to the thread self-locking principle, the position of the sliding block 6 on the screw 4 is not affected by the gravity of the heating device 5, and the position adjustment is completed. However, in order to better fix the posture of the heating device 5, the lock nut is screwed, and the posture of the heating device 5 is forced to be more stable by the friction force between the base 8 and the heating device 5.
The embodiment has the advantages that compared with the prior art:
(1) The positions of the two groups of heating devices 5 are adjusted through the screw 4, so that the screw is rapid and convenient, bolts are not required to be frequently disassembled and assembled, and the workload is small.
(2) The main components are all positioned in the base 8, so that the structure is compact and the occupied space is small.
(3) The position of the heating device 5 is adjusted by swinging, so that the device can adapt to the change of the diameter of a steel pipe in a larger range and has a larger application range.
(4) The locking nut is screwed, so that the posture of the heating device 5 is more stable.
(5) Compared with the traditional mechanism, the device does not need to detach the original induction heating coil or detach accessories of the matched waterway and circuit, reduces the working content, saves time, reduces the variety of the needed induction heating coil, and has better adaptability.
In a word, the device can conveniently and rapidly adjust the posture of the heating device 5, is suitable for different pipelines with larger diameter ranges, has good applicability, compact structure, convenient adjustment, small occupied space and high operation efficiency.
